What are common dive planning tools used by EANx divers?

The use of dive tables specific to the gas mix and software is essential for EANx (Enriched Air Nitrox) divers to ensure safe and effective dive planning. Enriched air nitrox contains a higher percentage of oxygen than air, which means it has different no-decompression limits and maximum operating depths compared to regular air. Therefore, using dive tables tailored to the specific gas mix allows divers to accurately calculate their allowable dive times and depths, minimizing the risk of oxygen toxicity and nitrogen narcosis.

In combination with dive planning software, which can help calculate various dive scenarios, divers can factor in specific variables such as the percentage of oxygen in the mix, planned depth, and duration of the dive. This enables a more comprehensive analysis of potential decompression requirements and overall dive safety.

The other options may involve useful tools or considerations for divers in general, but they do not specifically address the unique needs of enriched air divers or the importance of employing gas-specific calculations for safe dive planning. Standard dive tables and GPS devices do not cater to the nuances of different gas mixes, while underwater maps and swim timers, although helpful for navigation and time management under the water, do not replace the need for accurate dive planning based on gas mix.
